IMPROVEMENT IN FASTENINGS FOR BLIND-SLATS.

Specilicationforming part of Letters Patent No. 38,913, dated Julie 16,1863.

To all whom, it may concern,.-

Be it known that I, W. F. REDDING, of Utica, in the county of Oneida andState of New York, have invented a newand Improved Catch or Fasteningfor Blind-Slats; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, making a part of this specication, in which-Figure l is a face view of the inner side of a window-blind with myinvention applied to it; Fig. 2, avertical section of the same, taken inthe line x Fig. l; Fig. 3, a detached perspective view of the catch orfastening.

Similar letters of reference indicate corresponding parts in the severalgures.

This invention relates to a new and improved catch or fastening appliedto windowblinds, and arranged in such a manner that the slats of theblind may be secured in an open or closed state, and at different pointsbetween those two positions, as may be desired, the slats at the sametime being prevented from being moved from the outer side of the blind.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

Arepresents a window-frame, and B, a blind hinged or attached thereto inthe usual way. The blind is' constructed in the ordinary manner, a beingthe slats above the central crossrail of the blind, and c the slatsbelow it, and b b the rods to which the slats a a are respectivelyconnected. These parts, being all well known and of usual construction,do not require a minute description. The two Slat-rods b b are connectedby a wire link, C, as shown in Figs. l and 2, the ends of the link beingbent to form eyes, through which screws pass into the rods b b', asshown in Fig. 2. To the lower end of the lower rod, b', there isattached by a screw, c, a rod, D, which is bent at its lower end, andhas an eye, d, formed thereon, as shown in Fig. 3, the eye being thebent portion of the rod. To the lower cross-piece, e, of the blind Bthere is permanently secured a nieta-l plate, DX, to the lower part ofwhich a spring or elastic plate, E, is attached by a screw, e. Thisplate E is corrugated or bent transversely, so as to form recesses f,which are shown clearly in Figs. 2 and 3. These recesses f are of such awidth that they may receive the outer part of the eye d and hold orretain the same, as shown in Figs. 2 and 3. The spring or elasticity ofthe plate E is designed to be suiiicientto hold the eye d or keep thesame in the recesses j'. When the rod D is raised so that the eye d willit in the upper recesses f, the slats will be secured in a closed state,and the slats will be secured in a more or less open stateby adjustingthe eye d in the lower recess f. The rod D may be readily' adjusted overthe plate E by pressing the latter inward or toward the blind.

The invention is extremely simple, and may be applied at a small cost.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is v The rod D, secured to the lower end ofthe lower slat-rod, b, and provided with an eye, d, at its lower end, incombination with the spring or elastic plate E, provided with recesses fand secured to the lower crosspiece, e, of the blind, either with orwithout the plate DX, as and for the purpose herein set forth.
